The Well Tempered Lab LTD Symmetrex tonearm is a highly refined version of Bill Firebaugh’s famous “golf ball” tonearm. The Symmetrex tonearm configuration still uses a fully internally damped armtube and precision made golf ball suspended in silicone fluid for perfect damping, with the added advantage of enhanced trackability over even the most torturous groove modulation.
- 10.5’’ effective length (9″ version available)
- Fully internally damped armtube
- Adjustable tonearm damping via silicone fluid bath
- Simple azimuth adjustment
- Arm lift / cueing device
- Effective mass 10 grams
“The Symmetrex tonearm has the unique feature of dynamic tracking. The centre of gravity of the tonearm assembly is well above the rotational pivot of the ball and the ball is immersed in approximately 30% in the damping fluid. When the stylus encounters heavy modulation in the grooves the increased drag causes the tonearm to rotate down thus gently increasing the tracking force maintaining a secure and stable condition for every cartridge.”William Firebaugh, Chief Engineer
